Product Description

IAQ sensor 5-in-1 measurement of PM1.0, PM2.5, PM10, TVOC, HCHO, Particle number, support data storage and export Instructions for Use: When you use the BR-A air quality monitor, please shut it down regularly.If the TF memory card is full, please replace it with a new card in time. Otherwise, there may be a sudden automatic shutdown of the machine. Fault description: The machine suddenly shut down by itself, or plug it in and it won't charge, try the following steps to rectify the fault: Take out the TF memory card on the back of the machineAfter power off, connect the charger to charge for more than 6 hours and then turn it on without the TF memory card to see if it can work.If you need data logging, you can try to replace a new TF memory card into the machine to see if it works properly. 6-channel Particle Number 6-channel particle high precision laser sensor, 3-wire fan speed feedback, laser software compensation PM0.3PM0.5PM1.0PM2.5PM5.0PM10 Data Storage and Data Export Standard 128M data memory card that storage 100K+ data records Data storage frequency: once a minuteConnect the computer via Card ReaderData records can be exported in TXT file, users can convert it to EXCEL filePM1.0, PM2.5, PM10, CO2, TVOC, HCHO, Particle number 0.3 0.5 1.0 2.5 5.0 10 can be recorded Drawing 1hour , 12hours, 24hours air quality change curve, can intuitively distinguish the trend of air change 3 display modes: numerical display / Data curve display / particle number displayHistory can be directly queried on the machine Active air interaction system 3-way circular air convectionincreases contact area with the sensormute fan with low noise 12-bit AD signal amplifier chip Accurately distinguish tiny current signalsconvert the NA-level current amplification acquisition into a digital signalaccurately measure air pollutant concentration 48MHZ high frequency processing speed More sensitive measurementFaster algorithm responseHigh frequency data processing speed TVOC Total Volatile Organic Compounds TVOC is one of the three types that affect indoor air quality more seriously. Classification: Benzene, alkanes, aromatic hydrocarbons, alkenes, halogenated hydrocarbons, esters, aldehydes, ketones and others.Indoors, mainly from combustion products such as coal and natural gas, smoke from smoking, heating, and cooking, and adhesives, coatings, and paints in construction and decoration materials , Plate, wallpaper, etc., furniture, household appliances, furniture, detergents and human body emissions. There are nearly a thousand kinds. Particulate Matter PM stands for particulate matter (also called particle pollution): the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope. Particle pollution includes: PM10 : inhalable particles, with diameters that are generally 10 micrometers and smallerPM2.5 : fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. HCHO Formaldehyde Formaldehyde (HCHO) is a colorless, highly toxic, and flammable gas at room temperature. Formaldehyde is found in: Resins used in the manufacture of composite wood productsBuilding materials and insulationHousehold products such as glues, permanent press fabrics, paints and coatings, lacquers and finishes, and paper productsPreservatives used in some medicines, cosmetics and other consumer products A16 A17 A18 Add to Cart Buying Options Add to Cart Customer Reviews 3.7 out of 5 stars 22 2.9 out of 5 stars 8 3.5 out of 5 stars 55 Price $139.99$139.99 — no data $179.99$179.99 PM1.0 ✓ ✓ ✓ PM2.5 ✓ ✓ ✓ PM10 ✓ ✓ ✓ TVOC ✓ no data ✓ HCHO ✓ no data ✓ CO2 no data ✓ ✓ Particle Counter 0.3 0.5 1.0 2.5 5.0 10 ✓ ✓ ✓ Data Storage & Export ✓ ✓ ✓ About battery and charging: A16 has multiple built-in sensors, the power consumption is very high, please make sure to use a 2A adapter to charge it.Please do not use USB power supply, such a charging power is too small.In the power-on state, if the power of the adapter is too small, the charging speed will not keep up with the discharging speed when the machine is in use, and the machine will automatically shut down.If the machine shuts down automatically, please charge the machine for more than 6 hours in the shut down state before turning it on again.When the machine is turned on and used, it takes about 18 hours before the machine can be fully charged. So we generally recommend turning off and charging. Regarding machine reading is high on first use Reason: Because the packaging material itself contains interference gas, and it is sealed in the box for a long time, the charge attached to the surface of the sensor will increase, causing the value of the machine to be biased when it is turned on.Solution: After receiving the machine, put it in an outdoor clean and ventilated environment for about 8 hours, so that the charge can be released. (Charger can be connected to ensure the power supply) Regarding the high TVOC level Please check your measuring point if there are some human activities such as cooking, smoking, drinking or some chemical gases such as perfume, air freshener, detergent, etc. Then try to put the machine in an outdoor clean and ventilated environment for more than three hours to see if the machine value will drop.
